h//2π

reduced Planck constant

Planck's angular constant

h//2π

suuruse „mõju“ mõõtühiku nimetus/tähis SI välises looduslike ühikute süsteemis

name/symbol of the unit of action in non-SI system of natural units

taandatud Plancki konstant

Usage examples

Kvantmehaanika arvutustes ilmub Plancki konstant h väga tihti läbijagatuna 2π-ga, mistõttu on tähistuse lühendamiseks kasutusele võetud Plancki nurkkonstant ehk taandatud Plancki konstant tähisega h/2π.

Plancki nurkkonstant

h//2π symbol

Usage examples

h//2π = 1,054 571 628(53)·10-34 J·s.

reduced Planck constant

Usage examples

In quantum mechanical calculations, Planck's constant h frequently appears divided by 2π; therefore, to simplify notation, the angular Planck constant or reduced Planck constant denoted by h/2π has been introduced.
